GIRDER GRID FOR DEVELOPING LOFTS OR FOR ERECTING HALL- TYPE BUILDINGS

摘要

In the case of a girder grid for developing lifts or for erecting hall-type buildings, having load-bearing bends which are arranged at distances apart from one another and comprise profiled load-bearing members which are routed in the form of a polygonal progression in one plane, provision being made, in said girder grid, for the polygonal-progression load-bearing bends to comprise an angled strut 1, a second leg 3 and a beam 4 which can be connected to the strut 1, it is proposed, for the purpose of erecting hall-type buildings or for developing lofts quickly and cost-effectively, that the other end of the beam 4 be connectable to a joist rail 5 and the head 6 of the strut 1 and the beam end 7, which can be connected to the latter, each have two boundary surfaces 8, 9, of which the extensions intersect at a line of intersection which is normal to the load-bearing-bend plane, an obtuse angle being formed in the process, and a recess 10 for receiving an auxiliary rod 11 in the direction normal to the load-bearing-bend plane is provided in the vertex region of said angle.
